Patriots quarterback Brady also returns to work after missing day with left shoulder injury

The New York Giants quarterback was back at practice Thursday after missing part of the previous day’s workout with “a stomach bug.”

“I’m 100 percent,” Manning said after practicing for Sunday’s NFC title game against the 49ers in San Francisco. “I had a full practice today, did everything, took every rep. I feel good.”

Manning felt sick after waking up Wednesday. He “toughed it out” and attended team meetings and took part in the walk-through portions of practice.

“It wasn’t going well so I tried to be smart,” said Manning, who received intravenous fluids after leaving practice Wednesday.

Meanwhile, Patriots QB Tom Brady returned to the field after being out the previous day resting his left, non-throwing shoulder
